Removal of pitcher

[parrothead]

In a tournament this past weekend, the opposing coach made a mistake and made a trip to the mound which resulted in them having to change pitchers, they swapped the P and the 3B, who had pitched earlier in the game, which no issues there as softball (that I know of unless local rules) there is no limit to bringing a P back.

However, obviously he did not want to do this as the 3B threw one pitch, he went out again and swapped them back. I was always under the impression in a forced sub situation (like P throws warm up pitches or is on lineup card etc) that they had to face/complete one batter.
